这个命令很不寻常,其他人抱怨很难找到。
该命令是通用的,参数特定于要设置的开关。

嗨现在,我能够从PNA产生脉冲射频信号,但现在我面临着两个不同的问题1.当我在* 10uSec脉冲宽度&
在PNA中10毫秒脉冲周期(1%占空比)*然后IFBW自动设置为50Hz&
之后我无法改变IFBW,但它应该大于脉冲T ON时间的倒数。
另一方面,当我在* 10uSec脉冲宽度&处于手动配置脉冲时
在PNA中10毫秒脉冲周期(1%占空比)*然后IFBW自动设置为150KHz。
在IFBW 150KHz,我的阅读效果更好。
在PNA中以编程方式配置脉冲后,您能说出如何配置IFBW吗?
2.当我使用峰值检测器在CRO上看到生成的脉冲RF信号时,我发现生成的脉冲在其高状态和放大器中具有正斜率的斜坡。
也有崛起和
下降时间大于400nSec。
你能告诉它是PNA问题还是我必须使用其他一些设置来纠正生成的脉冲等待你的回复编辑:RVV on Aug 13,2013 12:11 AM

hi Gary
Now I am able to generate pulsed RF signal from PNA but now I am facing two different problems
1. when I am configuring pulse from LabVIEW at *10uSec pulse width & 10mSec pulse period (1% Duty Cycle)* in PNA then IFBW automatically set at 50Hz & after that I am not able to change the IFBW but it should be greater than the reciprocal of T ON time of pulse.
On the other hand when I am configuring the pulse Manually at *10uSec pulse width & 10mSec pulse period (1% Duty Cycle)* in PNA then IFBW automatically set at 150KHz.
At IFBW 150KHz my reading are better. Can you tell how to configure IFBW after configure pulse programmatically in PNA?
2. When I was seeing Generated pulse RF signal on CRO using Peak Detector, I found that generated pulse has a ramp with positive slope in its High State & also has rise & fall time greater than 400nSec.
Can you tell is it a PNA problem or I have to use some other settings to correct the generated pulse
Waiting for your reply
